Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to an automatic clamping CNC lathe. Background Technology

[0002] In the field of CNC lathe machining, the efficiency of automatic workpiece clamping and unloading is a key factor affecting machining continuity and production efficiency.

[0003] In the machining of cylindrical workpieces, traditional CNC lathes typically require a separate unloading mechanism to unload the completed cylindrical workpiece. The clamping mechanism and the unloading mechanism are independent of each other, resulting in a complex equipment structure, large space occupation, and potentially loose coordination between the two actions, affecting the machining rhythm. Furthermore, it is necessary to first activate a separate unloading device to remove the completed workpiece, and then complete the loading through the clamping mechanism. These two actions are executed independently, increasing time costs. Moreover, during continuous machining, if the completed workpiece is not removed in time, it may collide with the new workpiece being clamped, leading to workpiece damage or equipment failure.

[0004] Therefore, it is necessary to provide an automatically clamping CNC lathe to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides an automatic clamping CNC lathe that solves the problems mentioned in the background art.

The finger cylinder is fixedly connected to the telescopic end of the assembly cylinder. The clamping component is set on the clamping finger of the finger cylinder. The clamping component can clamp the workpiece. The clamping fingers of the finger cylinder are symmetrical front and back. The bottom of the clamping component of the front clamping finger is fixedly connected to a protrusion plate. The assembly cylinder can push the finger cylinder, the clamping component, and the protrusion plate to slide up and down relative to the operating chamber.

[0007] A guide plate is provided below the clamping turntable. When the assembly cylinder pushes the finger cylinder, clamping parts and cam plate to slide down to send the new workpiece to the clamping part of the clamping turntable, the cam plate pushes the previously completed workpiece onto the guide plate and discharges it out of the bed frame.

[0008] Preferably, the bed frame is provided with a feeding assembly, which includes: a feeding cylinder, a feeding column, a trough, a feeding inlet, and a feeding pipe. The feeding cylinder is fixedly installed on the left side of the bed frame, the feeding column is fixedly connected to the telescopic end of the feeding cylinder, the trough is opened inside the bed frame and is adapted to the feeding column, the top of the trough is provided with a feeding inlet, the trough extends to the left inner wall of the operating compartment, and the feeding pipe is fixedly connected to the left inner wall of the operating compartment, with the trough and the feeding pipe on the same axis.

[0009] Preferably, the feeding cylinder can drive the feeding column to push the cylindrical workpiece from the material trough through the material pipe to the clamping parts.

[0010] Preferably, the top of the bed frame is hinged with a flip cover, and the flip cover is also fixedly connected with an adapter compartment that is compatible with the assembled cylinder. The bottom of the bed frame is fixedly connected with multiple legs to support the entire device.

[0011] Preferably, a top frame is slidably mounted inside the operating chamber, a top cylinder is fixedly installed on the top frame, and a top rod is fixedly connected to the telescopic end of the top cylinder. The top rod and the clamping turntable are located on the same axis, and the top rod is used to push the workpiece into the clamping turntable.

[0012] Preferably, the operating chamber is provided with a tool holder one and a tool holder two. Tool holder one can slide left and right in the operating chamber, and tool holder two can slide back and forth on the top of tool holder one. A machining tool can be installed on tool holder two.

[0013] Preferably, the assembly cylinder is externally fixedly connected to a mounting bracket, and the assembly cylinder is fixedly installed in the operating chamber through the mounting bracket. The finger cylinder is fixedly connected to the telescopic end of the assembly cylinder, and the clamping component is fixedly connected to the two clamping fingers of the finger cylinder.

[0014] Compared with related technologies, the automatic clamping CNC lathe provided by this utility model has the following beneficial effects:

[0015] When the clamping component moves down with the assembly cylinder to clamp a new workpiece, its bottom convex plate simultaneously pushes the completed workpiece to the guide plate. The loading and unloading process is completed in a single action, avoiding the time loss caused by the independent execution of clamping and unloading in traditional equipment. At the same time, the convex plate and the clamping component move synchronously to ensure that the completed workpiece is pushed away from the processing area in a timely and stable manner during the clamping of the new workpiece, avoiding damage or equipment failure caused by collision between the new and old workpieces.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 5 An automatic clamping CNC lathe includes: a bed frame 10, an operating chamber 20, a first tool holder 30, a second tool holder 31, a top mount 40, a clamping rotary table 50, a feeding assembly 60, a clamping assembly 70, and a guide plate 80. The operating chamber 20 is located within the bed frame 10, and both the first and second tool holders 30 and 31 are located within the operating chamber 20. The first tool holder 30 can slide left and right within the operating chamber 20 via a drive assembly, and the second tool holder 31 can slide back and forth on top of the first tool holder 30 via a drive assembly. The second tool holder 31 can be used to mount cutting tools. The top mount 40 is slidably mounted inside the operating chamber 20 via a drive mechanism. The clamping rotary table 50 is fixedly mounted on the inner left side wall of the operating chamber 20. The workpiece 60 is mounted on the bed frame 10, and the clamping assembly 70 is mounted inside the operating chamber 20, with the clamping assembly 70 located directly above the clamping turntable 50. The guide plate 80 is located below the clamping turntable 50 and extends through to the back of the bed frame 10. The cylindrical workpiece is fed into the clamping assembly 70 by the feeding assembly 60. The clamping assembly 70 delivers the cylindrical workpiece to the clamping part of the clamping turntable 50. The tool holder 30 drives the tool holder 31 to slide inside the operating chamber 20, transporting the tool holder 31 to the front of the clamping turntable 50. The tool on the top of the tool holder 31 is used to process the cylindrical workpiece. After processing, the workpiece is transported to the outside of the bed frame 10 by the guide plate 80. The driving mechanism can be a lead screw and nut mechanism.

[0024] The clamping turntable 50 can be a chuck, jaws, etc., to clamp the workpiece, and the clamping turntable 50 is usually equipped with a motor that drives the workpiece to rotate.

[0025] The top of the bed frame 10 is hinged with a flip cover 11, which can be closed when the device is working. An adapter compartment 111 is also fixedly connected to the flip cover 11. Multiple support legs 12 are fixedly connected to the bottom of the bed frame 10 to support the entire device.

[0026] A top cylinder 41 is fixedly installed on the top frame 40. A top rod 42 is fixedly connected to the telescopic end of the top cylinder 41. The top rod 42 and the clamping turntable 50 are located on the same axis. When the clamping assembly 70 transports the cylindrical workpiece to the clamping part of the clamping turntable 50, the top frame 40 slides to a suitable position and then activates the top cylinder 41. The extended top rod 42 can push the cylindrical workpiece into the clamping part of the clamping turntable 50.

[0027] The feeding assembly 60 includes: a feeding cylinder 601, a feeding column 602, a feeding trough 603, a feeding inlet 604, and a feeding pipe 605. The feeding cylinder 601 is fixedly installed on the left side of the bed frame 10. The feeding column 602 is fixedly connected to the telescopic end of the feeding cylinder 601. The feeding trough 603 is opened inside the bed frame 10 and is adapted to the feeding column 602. The feeding inlet 604 is provided at the top of the feeding trough 603. The feeding trough 603 extends to the left inner wall of the operating chamber 20. The feeding pipe 605 is fixedly connected to... The cylindrical workpiece is attached to the left inner wall of the operating chamber 20, and the material trough 603 and the material pipe 605 are on the same axis. The cylindrical workpiece enters the material trough 603 from the feed trough 604. The feeding cylinder 601 is activated, so that the feeding column 602 pushes the cylindrical workpiece to the material pipe 605 and then pushes it outward into the clamping assembly 70. When the feeding column 602 extends, it can prevent the cylindrical workpiece from entering the material trough 603 from the feed trough 604. After the feeding column 602 retracts, the cylindrical workpiece is fed back into the material trough 603 to wait for the next feeding.

[0028] The clamping assembly 70 includes: an assembly cylinder 701, a finger cylinder 702, a clamping component 703, and a protruding plate 704. The assembly cylinder 701 is externally mounted with a mounting bracket 7011, and is fixedly installed inside the operating chamber 20 via the mounting bracket 7011. When the flip cover 11 is closed, the assembly cylinder 701 is located within the adaptation chamber 111. The finger cylinder 702 is fixedly connected to the telescopic end of the assembly cylinder 701. The clamping component 703 is fixedly connected to the two clamping fingers of the finger cylinder 702, and the clamping fingers of the finger cylinder 702 are symmetrical front and rear. The protruding plate 704 is fixedly connected to the bottom of the clamping component 703 fixed to the front clamping fingers. The feeding cylinder 601 pushes the cylindrical workpiece between the two clamping components 703, and the assembly cylinder 701 extends... The telescopic end moves the thumb cylinder downward, causing the two clamping parts 703 to move the cylindrical workpiece to the clamping part of the clamping turntable 50. The push rod 42 pushes the cylindrical workpiece into the clamping turntable 50, which clamps the cylindrical workpiece. The finger cylinder 702 resets, and the tool holder 1 30 and tool holder 2 31 move according to the preset program. The clamping turntable 50 drives the cylindrical workpiece to rotate, and the tool on tool holder 2 31 processes it. After processing, tool holder 1 30, tool holder 2 31, and push rod 42 reset in sequence. The clamping parts 703 move downward again with the workpiece. At this time, the clamping turntable 50 releases the previously completed workpiece, and the convex plate 704 pushes the completed workpiece onto the guide plate 80 to prevent it from falling and to facilitate the clamping of the next workpiece.

[0029] The working principle of the automatic clamping CNC lathe provided by this utility model is as follows:

[0030] A cylindrical workpiece is placed into the feed slot 604 at the top of the bed frame 10 and falls into the material slot 603 inside the bed frame 10. The feeding cylinder 601 is activated, pushing the feeding column 602 to move axially along the material slot 603. The feeding column 602 pushes the workpiece in the material slot 603 forward and sends it through the material pipe 605 into the clamping assembly 70 in the operating chamber 20 (i.e., between the two clamping components 703). After the feeding column 602 retracts, the next workpiece falls into the material slot 603 from the feed slot 604 and waits for the next push, thus realizing continuous feeding.

[0031] Assembly cylinder 701 is fixed inside operating chamber 20 by mounting bracket 7011. Its telescopic end is connected to finger cylinder 702. Clamping component 703 is installed on the clamping finger of finger cylinder 702. A protruding plate 704 is fixed to the bottom of the front clamping component 703. Assembly cylinder 701 drives finger cylinder 702 and clamping component 703 to move downward. Clamping component 703 clamps a new workpiece from feeding assembly 60 (through the clamping action of finger cylinder 702) and sends the new workpiece to the clamping part of clamping turntable 50. Top cylinder 41 and top rod 42 are installed on top frame 40 inside operating chamber 20. Rod 42 is coaxial with the clamping turntable 50. When the clamping component 703 sends the new workpiece to the vicinity of the clamping turntable 50, the top cylinder 41 extends and the top rod 42 pushes the workpiece into the clamping position of the clamping turntable 50 to complete the clamping. During the process of the clamping component 70 moving down to feed the material, the protruding plate 704 moves down synchronously with the front clamping component 703. The clamping turntable releases the finished workpiece, and the protruding plate 704 pushes the finished workpiece that has been processed once on the clamping turntable 50, so that it falls off the clamping turntable 50 and slides onto the guide plate 80 below. The guide plate 80 pushes the finished workpiece out of the bed frame 10 to achieve unloading.

[0032] Tool holder 30 can slide left and right in the operating chamber 20 via a drive mechanism (such as a motor or cylinder). Tool holder 31 can slide back and forth on top of tool holder 30 via a drive mechanism. The machining tool is installed on tool holder 31. According to the machining requirements, tool holder 30 and tool holder 31 move according to a preset program to position the tool at the workpiece machining position. The clamping turntable 50 drives the clamped workpiece to rotate. The tool performs machining operations such as polishing on the workpiece. After machining is completed, tool holder 30 and tool holder 31 are reset, and the push rod 42 is retracted, waiting for the next clamping.
